Potable water supply in U.S. manned space missions

A historical review of potable water supply systems used in the U.S. manned flight program is presented. This review provides a general understanding of the unusual challenges these systems have presented to the designers and operators of the related flight hardware. The presentation concludes with the projection of how water supply should be provided in future space missions - extended duration earth-orbital and interplanetary missions and lunar and Mars habitation bases - and the challenges to the biomedical community that providing these systems can present.
